Black; apex of scutellum, clavus (excluding base and apex), 

 the adjacent margin of corium (more or less distinctly) , a median 

 fascia to corium connecting its inner apical angle with the costal 

 margin, lateral margins of the female abdomen (except sixth 

 segment) , an oblong lateral spot at apex of second, a subquadrate 

 lateral spot at apex of fourth and the lateral border of fifth 

 female abdominal segments, a median broadly triangular spot 

 on third female ventral segment, more or less extended forward 

 over the second one, and a more or less distinct spot on the 

 acetabula white; membrane hyaline with a very broad black 

 median fascia; antennae black or dark fuscous, first joint white 

 toward base ; rostrum black, apical two-thirds of second and the 

 whole third joint testaceous; legs black, inner (anterior) side of 

 front femora ferruginous, all of trochanters (except their apices) 

 and base of middle and hind femora white, tarsi brownish or 

 fuscous; coarsely and thickly punctate, more finely so on upper 

 side of head, corium only with the ordinary seriate punctation, 

 abdomen impunctate; head above, pronotum, and scutellum 

 rather longly and densely erectly pilose, venter sparingly so, 

 corium with a very short but rather thick erect pubescence 

 visible only from the side, the white median fascia of the corium, 

 underside of head, prosternum, pleura, and apical part of venter 

 more or less densely clothed with a silky silvery pilosity, a very 

 thick similar pilosity forming an oblique fascia on each side of 

 venter between apical lateral part of second segment and middle 

 of third segment, in the female connecting the white spots at 

 these places. Head almost as broad as base of pronotum, second 

 joint of antennae about twice the length of first, third conspicu- 

 ously shorter than second and longer than fourth. Pronotum 

 distinctly longer than broad. Scutellum with the median keel 

 anteriorly ending in a transverse elevation placed a little behind 

 the base, apex subcallose. Elytra considerably constricted be- 

 fore middle, clavus with black punctation. Legs longly erectly 

 pilose, hind femora slightly passing apex of abdomen, gradually 

 narrowing from the middle to the base, first joint of hind tarsi
